Background::Although overnight fasting is recommended prior to endoscopic retrograde cholangiopancreatography (ERCP), the benefits and safety of high-carbohydrate fluid diet (CFD) intake 2 h before ERCP remain unclear. This study aimed to analyze whether high-CFD intake 2 h before ERCP can be safe and accelerate patients’ recovery.Methods::This prospective, multicenter, randomized controlled trial involved 15 tertiary ERCP centers. A total of 1330 patients were randomized into CFD group ( n = 665) and fasting group ( n = 665). The CFD group received 400 mL of maltodextrin orally 2 h before ERCP, while the control group abstained from food/water overnight (>6 h) before ERCP. All ERCP procedures were performed using deep sedation with intravenous propofol. The investigators were blinded but not the patients. The primary outcomes included postoperative fatigue and abdominal pain score, and the secondary outcomes included complications and changes in metabolic indicators. The outcomes were analyzed according to a modified intention-to-treat principle. Results::The post-ERCP fatigue scores were significantly lower at 4 h (4.1 ± 2.6 vs. 4.8 ± 2.8, t = 4.23, P <0.001) and 20 h (2.4 ± 2.1 vs. 3.4 ± 2.4, t= 7.94, P <0.001) in the CFD group, with least-squares mean differences of 0.48 (95% confidence interval [CI]: 0.26–0.71, P <0.001) and 0.76 (95% CI: 0.57–0.95, P <0.001), respectively. The 4-h pain scores (2.1 ± 1.7 vs. 2.2 ± 1.7, t = 2.60, P = 0.009, with a least-squares mean difference of 0.21 [95% CI: 0.05–0.37]) and positive urine ketone levels (7.7% [39/509] vs. 15.4% [82/533], χ2 = 15.13, P <0.001) were lower in the CFD group. The CFD group had significantly less cholangitis (2.1% [13/634] vs. 4.0% [26/658], χ2 = 3.99, P = 0.046) but not pancreatitis (5.5% [35/634] vs. 6.5% [43/658], χ2 = 0.59, P = 0.444). Subgroup analysis revealed that CFD reduced the incidence of complications in patients with native papilla (odds ratio [OR]: 0.61, 95% CI: 0.39–0.95, P = 0.028) in the multivariable models. Conclusion::Ingesting 400 mL of CFD 2 h before ERCP is safe, with a reduction in post-ERCP fatigue, abdominal pain, and cholangitis during recovery.Trail Registration::ClinicalTrials.gov, No. NCT03075280.

Objectives: To evaluate the positive rate of left posterior lymph nodes of the superior mesenteric artery (14cd-LN) in patients undergoing pancreaticoduodenectomy for pancreatic head carcinoma,to analyze the impact of 14cd-LN dissection on lymph node staging and tumor TNM staging. Methods: The clinical and pathological data of 103 consecutive patients with pancreatic cancer who underwent pancreaticoduodenectomy at Pancreatic Center,the First Affiliated Hospital of Nanjing Medical University from January to December 2022 were analyzed,retrospectively. There were 69 males and 34 females,with an age(M (IQR))of 63.0 (14.0) years (range:48.0 to 86.0 years). The χ² test and Fisher's exact probability method was used for comparison of the count data between the groups,respectively. The rank sum test was used for comparison of the measurement data between groups. Univariate and multivariate Logistic regression analyzes were used for the analysis of risk factors. Results: All 103 patients underwent pancreaticoduodenectomy successfully using the left-sided uncinate process and the artery first approach. Pathological examination showed pancreatic ductal adenocarcinoma in all cases. The location of the tumors was the pancreatic head in 40 cases,pancreatic head-uncinate in 45 cases,and pancreatic head-neck in 18 cases. Of the 103 patients,38 cases had moderately differentiated tumor and 65 cases had poorly differentiated tumor. The diameter of the lesions was 3.2 (0.8) cm (range:1.7 to 6.5 cm),the number of lymph nodes harvested was 25 (10) (range:11 to 53),and the number of positive lymph nodes was 1 (3) (range:0 to 40). The lymph node stage was stage N0 in 35 cases (34.0%),stage N1 in 43 cases (41.7%),and stage N2 in 25 cases (24.3%). TNM staging was stage ⅠA in 5 cases (4.9%),stage ⅠB in 19 cases (18.4%),stage ⅡA in 2 cases (1.9%),stage ⅡB in 38 cases (36.9%),stage Ⅲ in 38 cases (36.9%),and stage Ⅳ in 1 case (1.0%). In 103 patients with pancreatic head cancer,the overall positivity rate for 14cd-LN was 31.1% (32/103),and the positive rates for 14c-LN and 14d-LN were 21.4% (22/103) and 18.4% (19/103),respectively. 14cd-LN dissection increased the number of lymph nodes (P<0.01) and positive lymph nodes (P<0.01). As a result of the 14cd-LN dissection,the lymph node stage was changed in 6 patients,including 5 patients changed from N0 to N1 and 1 patient changed from N1 to N2. Similarly,the TNM stage was changed in 5 patients,including 2 patients changed from stage ⅠB to ⅡB,2 patients changed from stage ⅡA to ⅡB,and 1 patient changed from stage ⅡB to Ⅲ. Tumors located in the pancreatic head-uncinate (OR=3.43,95%CI:1.08 to 10.93,P=0.037) and the positivity of 7,8,9,12 LN (OR=5.45,95%CI:1.45 to 20.44,P=0.012) were independent risk factors for 14c-LN metastasis; while tumors with diameter >3 cm (OR=3.93,95%CI:1.08 to 14.33,P=0.038) and the positivity of 7,8,9,12 LN (OR=11.09,95%CI:2.69 to 45.80,P=0.001) were independent risk factors for 14d-LN metastasis. Conclusion: Due to its high positive rate in pancreatic head cancer,dissection of 14cd-LN during pancreaticoduodenectomy should be recommended,which can increase the number of lymph nodes harvested,provide a more accurate lymph node staging and TNM staging.

Objective:The clinical characteristics and prognosis of 20 patients with small B-lymphocyte proliferative disease with t (14;19) (q32; q13) were analyzed to improve the understanding of such rare cases.Methods:The clinical data of 20 patients with t (14; 19) (q32; q13) small B lymphocyte proliferative disease treated in the First Affiliated Hospital of Nanjing Medical University from April 2013 to December 2020 were retrospectively collected and analyzed. Among them, 10 cases were chronic lymphocytic leukemia (CLL) and 10 cases were other small B-cell malignancies.Results:Among the 20 cases, 10 were male and 10 were female, and the median age at diagnosis was 53.5 (35-88) years old. All patients had absolute lymphocytosis, 19 patients had lymphadenopathy, and 10 patients had splenomegaly. With a median follow-up of 36 (4-163) months, three patients died, and 11 patients had a time to treatment (TTT) ≤12 months. Ten patients (50%) were accompanied by +12, two patients (2/17, 12%) were accompanied by 13q-. Moreover, we found that t (14;19) was associated with unmutated immunoglobulin heavy-chain variable (IGHV) somatic mutation (17/19, 89%) and a biased use of IGHV4-39 (7/17, 41%) was observed. Next-generation sequencing detected one or more gene mutations in 14 (14/17, 82%) cases and a total of 25 gene mutations had been revealed, of which the most frequent were NOTCH1 (35%) , followed by SF3B1 (24%) and KMT2D (18%) . For 10 CLL patients, five (50%) were defined as Rai Ⅲ/Binet C. It is noteworthy that among the 20 cases, two cases actually involved Richter transformation.Conclusions:Small B-cell malignant tumors with abnormal t (14; 19) show unique clinical biological characteristics, often accompanied by a variety of adverse prognostic factors, and tend to have an aggressive clinical course.

Objective:To investigate the clinical, genetic, and clonality related aspects of individuals with Richter transformation (RT) .Methods:From January 2019 to December 2021, 18 RT patients with diagnoses at the First Affiliated Hospital of Nanjing Medical University (Pukou CLL center) were retrospectively examined. The immunoglobin heavy variable (IGHV) gene usage and IGHV-D-J rearrangement pattern of diagnosed CLL/SLL and transformed diffuse large B-cell lymphoma (DLBCL) were compared to determine the clonality relatedness. To investigate the risk factors of RT, Clinical and laboratory data from patients with newly diagnosed CLL/SLL and transformed DLBCL were gathered.Results:The median age of RT was 56.5 (41-75) years old. 17 patients transformed to DLBCL and 1 transformed to Hodgkin lymphoma (HL) . Of 17 individuals who had DLBCL transformation, 15 had CLL/SLL-related clonality and 2 had unrelated clonality. Next-generation sequencing (NGS) analysis of 11 paired initially diagnosed treatment-naive CLL/SLL and RT DLBCL found that EGR2、TP53 and NOTCH1 were among the most frequently mutated genes both in treatment-naive CLL/SLL and in RT DLBCL. In several cases, specific mutations were gained or lost throughout RT, indicating clonal evolution. Among 10 patients before exposure to BTK inhibitors before RT, four patients acquired BTK mutation. The aforementioned mutations should be considered high-risk variables for transformation; in addition, TP53 and EGR2 mutations could be linked to a poor prognosis following RT in patients receiving a cocktail of new medicines.Conclusion:Most RT DLBCL patients in our center are clonality related (15/17, 88.2% ) and we recommend all qualified centers to evaluate clonality relatedness of RT DLBCL patients. There was some variability in the mutational landscape between DLBCL that had undergone a transformation and initially diagnosed, treatment-naive CLL/SLL. The underlying molecular mechanism of RT needs more research.

We were interested in ascertaining differences in developmental neurotoxicity in normal and blood-stasis pregnant mice administered orally Rhizoma Curcumae and the underlying molecular biology mechanisms of any differences. To answer these questions, a blood stasis model was induced by being immersion in ice water. C57BL/6 mice with blood stasis, normal C57BL/6 mice, Nrf2 knock out (KO) mice with blood stasis were randomized into control groups and Rhizoma Curcumae exposure groups. The pregnant mice were administered Rhizoma Curcumae during pregnant day 5 to day 18. The neurodevelopment reflex was examined by the positive occurring time of avoidance precipice reflex tests. Measurement of glutathione (GSH) in brain of the offspring was performed by colorimetric assays. Transcription factor NF-E2-related factor 2 (Nrf2), glutamate cysteine ligase catalytic subunit (GCLc), and glutamate cysteine ligase modifier subunit (GCLm) mRNA and protein expression in brain of the offspring were examined by real-time RT-PCR and Western blot, respectively. All animal care and experiments procedures were reviewed and approved by the Animal Care and Use Committee of Qiqihar Medical College. Our results demonstrated for the first time evidence that C57BL/6 mice treated with Rhizoma Curcumae (10.0 g·kg^-1) extended the positive occurring time of avoidance precipice reflex tests of offspring mice compared with the normal control group (P<0.05). We could not find any significant change in that of blood-stasis pregnant mice offspring compared with the normal control group (P>0.05). Compared with the normal control group, level of glutathione, mRNA and protein expression of Nrf2, GCLc, and GCLm significantly increased in brain of the offspring of blood-stasis pregnant mice (all P<0.05). However, mice treated with Rhizoma Curcumae (10.0 g·kg^-1) did not change those of offspring (all P>0.05). Knock out Nrf2 using CRISPR/Cas9 extended the positive occurring time of avoidance precipice reflex tests of offspring of blood-stasis pregnant mice (P<0.05). To conclude, developmental neurotoxicity of the blood-stasis pregnant mice to Rhizoma Curcumae was weaker than that of the normal pregnant mice. Cold-induced Nrf2 activation has important roles in "YOU-GU-WU-YUN" phenomenon of Rhizoma Curcumae.

OBJECTIVE: To analyze the 5 experimental indexes of CDSS in the patients with acute leukemia (AL) so as to provide the laboratorial basis for the early diagnosis and treatment of the secondary DIC in AL. METHODS: Three hundred and thirty three patients with AL were divided into 7 groups, such as AML-M1-M5, other AML and ALL. The experimental indexes and CDSS scores of all AL groups were compared and analyzed in pairs, meanwhile 100 healthy persons were taken in the control group. Clinical events such as early death in all cases were also analyzed. RESULTS: The highest positive rate of Platelet was 59.76%, among the 5 experimental indexes, followed by D-D (30.93%), and the lowest APTT with only 2.70%. Compared with the control group, the differences of remaining indexes were statistically significant (P＜0.01), except APTT in group AML-M3 and FIB in the other AML groups. The score of laboratory index was (1.50±1.51) in all AL patients, and the positive rate of overt DIC ( score≥4) was 14.11% ( 47 cases). The highest score of CDSS was (3.34 ±1.71) in group AML-M3. The difference in the incidence of early death and cerebral (pulmonary) hemorrhage in DIC patients were statistically significant (P＜0.05 and P＜0.01). CONCLUSION The application of quantitative integral method of experimental indexes in CDSS is objective and feasible, which is of great significance for early diagnosis and early treatment of acute leukemia complicated with DIC.

OBJECTIVE: To compare the clinical outcomes of microfracture and autogenous osteochondral mosaic transplantation in the treatment of knee joint cartilage injury. METHODS: A retrospective analysis of 71 patients with articular cartilage defects on the femoral condyles who were by autogenous osteochondral mosaic transplantation or microfracture from February 2011 to February 2016, and these patients were followed up for at least 2 years. According to the sugical procedures, the patients were divided into two groups. In the microfracture group, there were 33 patients, 20 males and 13 females, with a mean age of(28.1±4.2) years old; in the mosaicplasty group, there were 38 patients, 26 males and 12 females, with a mean age of(27.8±3.5) years old. The Lysholm knee score, Hospital for Special Surgery (HSS) knee score and the Ahlbäck classification grade were recorded to evaluate the clinical efficacy. Complications were also recorded. RESULTS: The mean Lysholm scores of the microfracture group and the mosaicplasty group improved from 62.9±6.8 and 60.3±7.5 preoperatively to 77.0±5.4 and 85.8±5.6 post-operatively, respectively(<0.05). Mean HSS scores of the microfracture group and the mosaicplasty group improved from 81.5±7.6 and 79.6±8.6 preoperatively to 88.0±4.7 and 91.9±4.7 post-operatively, respectively(<0.05). The mean Lysholm score and HSS score were significantly higher in the mosaicplasty group than those in the microfracture group at the latest follow-up. One patient in the mosaicplasty group suffered superficial wound infection. During the follow-up, no knee osteoarthritis was observed in two groups. CONCLUSIONS Autogenous osteochondral mosaicplasty and microfracture are proved to be safe and effective procedures for knee articular cartilage defects. However, the mosaicplasty has better clinical outcome than the microfracture.

The ventral pallidum (VP) is a crucial component of the limbic loop of the basal ganglia and participates in the regulation of reward, motivation, and emotion. Although the VP receives afferent inputs from the central histaminergic system, little is known about the effect of histamine on the VP and the underlying receptor mechanism. Here, we showed that histamine, a hypothalamic-derived neuromodulator, directly depolarized and excited the GABAergic VP neurons which comprise a major cell type in the VP and are responsible for encoding cues of incentive salience and reward hedonics. Both postsynaptic histamine H1 and H2 receptors were found to be expressed in the GABAergic VP neurons and co-mediate the excitatory effect of histamine. These results suggested that the central histaminergic system may actively participate in VP-mediated motivational and emotional behaviors via direct modulation of the GABAergic VP neurons. Our findings also have implications for the role of histamine and the central histaminergic system in psychiatric disorders.

Individual identification by measuring the human skeleton is an important research in the field of forensic anthropology. Computed tomography （CT） technology can provide high-resolution image of skeleton. Skeleton image can be reformed by software in the post-processing workstation. Different skeleton measurement indexes of anthropology, such as diameter, angle, area and volume, can be measured on section and reformative images. Measurement process is barely affected by human factors. This paper reviews the literatures at home and abroad about the application of measuring skeleton by CT in forensic anthropology research for individual identification in four aspects, including sex determination, height infer, facial soft tissue thickness measurement and age estimation. The major technology and the application of CT in forensic anthropology research are compared and discussed, respectively.

OBJECTIVETo assess the effect and safety of Jinhua Qinggan Granule (JHG) in treating influenza patients of wind-heat affecting Fei syndrome (WHAFS).

METHODSTotally 136 influenza patients of WHAFS were randomized by stratification into 3 groups, the high dose JHG group (44 cases, 10 g each time), the low dose JHG group (45 cases, 5 g JHG + 5 g placebo each time), and the placebo control group (47 cases, 10 g placebo each time). All medication was administered three times daily for 5 days. The fever disappearance time, the fever disappearance rate, efficacy of TCM syndrome, the disappearance rate of main symptoms and physical signs of flu, the negative rate of virus nucleic acid in the pharyngeal secretion, and safety indicators were assessed.

RESULTSThe median fever disappearance time was 32.8 h (95% CI: 22.5-41.0 h) in the high dose JHG group, 26.0 h (95% CI: 14.5-36.5 h) in the low dose JHG group, 39.5 h (95% CI: 29.0-46.0 h) in the placebo control group. There was statistical difference in the median fever disappearance time between the low dose JHG group and the placebo control group (P = 0.011). Three days after treatment, the markedly effective rate of TCM symptoms in the low dose JHG group was 66.7%, higher than that of the placebo control group (38.3%), and its effective rate was superior to that of the high dose JHG group (P = 0.043). Five days after treatment, the recovery rate of the low dose JHG group (42.2%) was higher than that of the high dose JHG group (25.0%, P = 0.026) and that of the placebo control group (14.9%, P = 0.002). The markedly effective rate of the low dose JHG group (86.7%) was higher than that of the placebo control group (55.3%, P = 0.001). Similar effects were obtained in the low dose JHG group and the high dose JHG group, but slightly poor in partial indicators of the high dose JHG group. There was no statistical difference in adverse reaction among these three groups (P > 0.05).

CONCLUSIONSJHG was effective and safe in treating influenza patients of WHAFS. Routinely low dose was the optimal dosage of JHG.
